POKE-YOKE.

SPECIFICATION forming part of Letters Patent No. 419,138, dated January'7, 1890.

Application filed July 24, 1889. Serial No. 318,600. (Model.)

To @ZZ whom, it may concern:

Be it known that I, ARCH BOLDING, a citizen of the United States,residing at Sumner, in the county of Lawrence and State of Illinois,have invented a new and useful Improvement in Poke-Yokes, of which thefollowing is a specification.

This invention relates to certain new and useful improvements inanimal-pokes, and the novelty resides in the peculiar combinations andthe construction, arrangement, and adaptation of parts, all as morefully hereinafter described, shown in the drawings, and thenparticularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspeciiication, and in whichw Figure lis a perspective view of myimproved poke. Fig. 2 is a like view from t-he reverse side.

Like letters of reference indicate like parts in both views.

Referring now to the details of the drawings by letter, A designates thestang, to which is pivoted the neck-yoke B, the said yoke beingpivotally connected with the stang by means of a cross shaft or pin a,remov ably held in position by means of a removable pin b, having anopening in its end through which passes the said pin, the pin beingconnected to the yoke by a chain or cord c. On this pin or shaft betweenthe bow and the stang are the blocks O, which serve to keep the stangsubstantially in the center of the space between the sides of the bow oryoke. The sides vot the yoke are provided with a series of holes, bymeans of which and the removable pin the size of the yoke may beincreased or diminished when desired.

C is the breast-piece, from which extend the parallel arms A', betweenthe free ends of which the end of the stangis pivoted upon a transversepivot d.

B is a spring-brace connected at one end to the stang and at the otherend provided with a spring-catch e, designed to engage under a keeper fon the breast-piece, a slot being provided beneath the keeper to receivethe spring catch, as clearly shown. The

spring-brace is connected with the breast piece by means of thespring-arms D, of wire, which have their bights arranged in slots in thespring-brace and their ends secured in the breast-piece, as shown, thesaid ends passing loosely through openings in the said breast-piece andbeing sharpened, as shown, so that as the breastpiece is pushed forwardby the animal the sharpened ends of the wires will prick him. Thespringcatch on the spring-brace has a turnedup end, which serves tolimit its movement in one direction and prevents the withdrawal of thewires from their openings in the breast-piece, yet allowing freemovement of the wires toward the animal.

That I claim as new isl. The combination, with the stang and the yokepivoted thereto, of the breast-piece pivotally connected with the stang,and the spring-brace connected with the stang and carrying the wires,the ends of which pass loosely through the breast-piece, substantiallyas described.

2. rlhe combination, with the stang and the yoke pivotally connectedtherewith, of the breast-piece, the parallel arms on the breastpiecepivotally connected with the end of the stang, and the spring-braceconnected at one end with the stang and at the other movably connectedwith the breast piece and carrying the pricking-wires, substantially asdescribed.

The combination, with the stang and the yoke pivotally connectedtherewith, of the breast -piece, the parallel arms projecting therefromand pivotally connected with the end of the stang, the spring-braceconnected at one end to the stang and at the other end movably engagedwith the breast-piece and carrying a catch having upturned end, a keeperfor said catch on the breast-piece, and the wire arms connected with thespringbrace and having their ends passed loosely 95 through thebreast-piece, substantially as and for the purpose specified.
